Benefits of technology
This patent aims to provide a better way to refurbish a BOP (Blowout Preventer) after it is worn out. The invention includes a single replaceable insert that can be easily replaced after the BOP is no longer working properly. This saves money and reduces the amount of work needed to repair the BOP. Additionally, the invention avoids the need for welds and heat treatments to refurbish the ram cavity of the BOP, which makes it a more reliable and cost-effective option.
Problems solved by technology
At the end of the lifetime of a blowout preventer, numerous problems may exist in the body of the BOP, which prevent the rams from sealing within the BOP body.
Also, there is high chance of crack development if the procedure is not followed properly, directly affecting the performance of refurbished BOP.

A replaceable seat seal is used to form a replaceable portion of the ram cavity in a BOP that allows the upper central portion of the ram cavity to be replaced when wear occurs. A method is provided to produce a BOP that with a replaceable portion of the ram cavity. The single piece insert, also referred to as a single insert, utilizes only the single insert to repair the BOP as compared to another design that comprised a top insert, bottom insert, and two side inserts. The top insert of the prior art is comparable in construction and mounting position to the single insert.
Description
BACKGROUND OF THE INVENTIONField of the Invention[0001]The present invention relates generally to used blowout preventers that must be repaired and refurbished and more particularly to a replaceable single piece replaceable insert that may be used instead of the prolonged process of repair of BOP bodies. However, the present invention could also be utilized in new blowout preventers to provide a single piece replaceable insert that can be changed at the location.Background of the Invention[0002]A blowout preventer (BOP) is a large, specialized valve or similar mechanical device, used to seal, control and monitor oil and gas wells to prevent blowouts, the uncontrolled release of crude oil and / or natural gas from a well. They are usually installed redundantly in stacks.[0003]The BOP housing (body) has a vertical well bore or throughbore and a horizontal ram cavity (ram guide chamber). Opposing rams (plungers) in the ram cavity translate horizontally to overcome downhole pressures and ...
